Description

Technical Field

[0001] The present invention belongs to the technical field of vehicle logo switching, and in particular relates to a vehicle logo switching device and a control method. Background Art

[0002] As the most intuitive and representative external symbol of a car brand, the car logo is an indispensable part of the vehicle. It not only carries the brand's history and culture, but also reflects its market positioning and consumer base. With the continuous development and intensified competition in the automotive market, the design and display of the car logo have become a key focus for major automakers.

[0003] Initially, most car logos were fixed; once installed, they could not be replaced or adjusted. This design was simple and cost-effective, but lacked flexibility and diversity. To further enhance the flexibility and diversity of car logos, logo switching devices were developed. These devices allow car owners to quickly switch between different logo styles or patterns based on personal preference or specific scenarios without having to replace the entire logo. The advent of these devices has greatly expanded the options for personalized car decoration.

[0004] However, existing car logo switching devices usually use a lifting structure to achieve the switching of the car logo. This switching method has a complex mechanism and a slow switching speed. It is not suitable for scenes that require fast switching of the car logo, and it occupies a large space in the height direction. Summary of the Invention

[0052] The following is a detailed description of a vehicle logo switching device and control method proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description and claims.

[0053] Example 1

[0054] See Figures 1 to 7 In one embodiment, a vehicle logo switching device is provided for performing a vehicle logo switching operation at a vehicle logo opening of an external vehicle shell 10, and includes a base shell 1, a track guide portion 4, a first vehicle logo carrier, a second vehicle logo carrier, and a driving portion 2.

[0055] The base shell 1 is configured to cooperate with the outer shell 10 to form a logo switching space, and the logo switching space is defined as having a horizontal length, a longitudinal width, and a vertical height.

[0056] The track guide portion 4 is mounted on the base housing 1 and forms a guide track within the vehicle logo switching space. The guide track comprises a display track segment 7 located directly below the vehicle logo opening, and a first switching track segment and a second switching track segment extending laterally outward from both ends of the display track segment 7. At least a portion of the first switching track segment and at least a portion of the second switching track segment are lower in height than the display track segment 7.

[0057] The first logo carrier is configured to be limited by the track guide 4 so as to move along the guide track. The second logo carrier is also configured to be limited by the track guide 4 so as to move along the guide track. The drive unit 2 is mounted on the base housing 1. The output end of the drive unit 2 is connected to the first and second logo carriers. The drive unit 2 is configured to drive the first and second logo carriers to switch between the first and second display configurations.

[0058] In the first display configuration, the output end of the drive unit 2 moves to the first position, the first logo carrier is located in the first switching track segment, and the second logo carrier is located in the display track segment 7 and corresponds to the vehicle shell opening. In the second display configuration, the output end of the drive unit 2 moves to the second position, the first logo carrier is located in the display track segment 7 and corresponds to the vehicle shell opening, and the second logo carrier is located in the second switching track segment.

[0059] In this embodiment, a vehicle logo switching space is formed by setting a base shell 1 and cooperating with an outer vehicle shell 10, and a track guide part 4, a first vehicle logo carrier, a second vehicle logo carrier and a driving part 2 are set in the vehicle logo switching space; a guide track including a first switching track segment, a display track segment 7 and a second switching track segment is formed on the track guide part 4, and the two switching track segments are set to extend laterally outward and at least partially lower than the display track segment 7 to serve as a temporary storage area for the vehicle logo, and the driving part 2 is used to drive the two vehicle logo carriers to move along the guide track between the first display configuration and the second display configuration; in the first display configuration, the first vehicle logo carrier is hidden in the first switching track segment, the second vehicle logo carrier is located in the display track segment 7 and the vehicle logo thereon is at the vehicle logo opening of the outer vehicle shell 10; In the second display configuration, the first vehicle logo carrier and the second vehicle logo carrier move to the other side as a whole, the first vehicle logo carrier moves to the display track section 7 and the vehicle logo thereon is at the vehicle logo opening of the outer vehicle shell 10, and the second vehicle logo carrier moves and is hidden in the second switching track section, thereby realizing the vehicle logo switching action. Moreover, in this embodiment, since the moving direction is horizontal, the height difference between the two switching track sections relative to the display track section 7 only needs to meet the thickness of the corresponding vehicle logo carrier, and the space occupied by the overall device in the height direction can be greatly reduced. Moreover, this form of structure for realizing vehicle logo switching by reciprocating movement along the guide track is also simpler than the solution of lifting two vehicle logos, which solves the problems of complex mechanism and large space occupied in the height direction in the existing lifting and switching vehicle logo methods.

[0060] The specific structure of the vehicle logo switching device of this embodiment is further described below:

[0061] In this embodiment, the base shell 1 specifically includes a bottom plate 101 and two connecting plates 102. The lower ends of the two connecting plates 102 are connected to the bottom plate 101 and are located at the longitudinal ends of the bottom plate 101. The upper ends of the two connecting plates 102 are used to connect to the outer shell 10. In other words, the bottom plate 101 and the two connecting plates 102 cooperate to form a rectangular space extending laterally on the bottom surface of the outer shell 10.

[0062] See Figure 6 In this embodiment, the first switching track segment includes a first temporary storage segment 5 and a first transition segment 6. The first transition segment 6 connects the first temporary storage segment 5 and the display track segment 7. The first transition segment 6 extends laterally outward and vertically downward relative to the display track segment 7. That is, the first temporary storage segment 5 and the display track segment 7 are parallel to each other, and the first temporary storage segment 5 is vertically lower than the display track segment 7. The first transition segment 6 is an oblique line segment or an arc segment connecting the first temporary storage segment 5 and the display track segment 7, and the connection between the first transition segment 6 and the display track segment 7 can be configured as an arc-shaped transition.

[0063] The second switching track segment includes a second temporary storage segment 9 and a second transition segment 8. The second transition segment 8 connects between the second temporary storage segment 9 and the display track segment 7. The second transition segment 8 extends laterally outward and vertically downward relative to the display track segment 7. That is, the second temporary storage segment 9 and the display track segment 7 are parallel to each other, and the second temporary storage segment 9 is vertically lower than the display track segment 7. The second transition segment 8 is an oblique line segment or an arc segment connecting the second temporary storage segment 9 and the display track segment 7, and the connection between the second transition segment 8 and the display track segment 7 can be set to an arc-shaped transition.

[0064] Among them, the first temporary storage section 5 and the second temporary storage section 9 are lower than the display track section 7, so that the corresponding vehicle logo carrier can be gradually lifted at the transition section and extended into the vehicle logo opening when moving from the corresponding temporary storage section toward the display track section 7 (from the perspective of the outside of the vehicle, that is, the vehicle logo on the vehicle logo carrier gradually enters the vehicle logo opening from the inside of the vehicle shell), that is, the height of the display track section 7 can meet the requirements of the vehicle logo entering the vehicle logo opening for display, and the display track section 7 only corresponds to the vehicle logo opening, and the transition sections on both sides are responsible for allowing the vehicle logo to gradually enter the vehicle logo opening, while the two outermost temporary storage sections are hidden under the vehicle shell.

[0065] In this embodiment, the specific structure of the track guide part 4 may include a first track plate 401 and a second track plate 402. The first track plate 401 and the second track plate 402 are both arranged in the horizontal direction and are respectively arranged on both sides of the driving part 2. The first track plate 401 and the second track plate 402 are respectively formed with a first track groove 403 and a second track groove on the surface facing the driving part 2. The extension direction of the first track groove 403 and the second track groove matches the guide track. The sliding connection can be achieved by providing a corresponding slider 203 or pulley structure on the vehicle logo carrier. In other embodiments, guide rails can also be provided on the first track plate 401 and the second track plate 402, and this can be achieved by providing a corresponding pulley on the vehicle logo carrier. This is not specifically limited here.

[0066] Furthermore, in order to minimize the gap between the car logo opening and the car logo as much as possible, and reduce the contact wear between the car logo and the car shell caused by the shaking or vibration of the car logo during rapid switching, the above-mentioned track guide part 4 can also include a first mounting seat, a second mounting seat, a tail shaft 406 and an elastic support member 407.

[0067] The first mounting seat and the second mounting seat are respectively mounted on the base shell 1 and are located on both sides of the driving unit 2. The head end of the first track plate 401 is rotatably connected to the first mounting seat with the rotation axis parallel to the longitudinal direction. The head end of the second track plate 402 is connected to the first mounting seat with the rotation axis parallel to the longitudinal direction. The two ends of the tail shaft 406 are respectively connected to the tail end of the first track plate 401 and the tail end of the second track plate 402. The elastic support member 407 is connected between the tail shaft 406 and the base shell 1. The elastic support member 407 is configured to provide the supporting force required by the tail shaft 406 and has a compression stroke and a tension stroke. The elastic member can specifically be a spring or other component that can output an elastic member. That is, the first track plate 401 and the second track plate 402 can both swing around the connection position between them and the corresponding mounting seat, and the swing amplitude is limited to a certain extent by the elastic support member 407, so that the vibration generated by the driving part 2 when driving the first vehicle logo carrier and the second vehicle logo carrier to move can be absorbed by the elastic member, and when the corresponding vehicle logo carrier is in a rapid movement process, the impact force generated on the vehicle logo carrier can be absorbed to a certain extent, thereby improving its service life.

[0068] In this embodiment, the driving portion 2 may specifically include a linear drive mechanism and an intermediate transmission member 204. The linear drive mechanism is mounted on the base shell 1, and the output end of the linear drive mechanism is configured to output a linear motion in the transverse direction. The intermediate transmission member 204 has a transmission input end and two transmission output ends. The transmission input end is rotationally connected to the output end of the linear drive mechanism, and the axis of rotation is parallel to the longitudinal direction. The two transmission output ends are rotationally connected to the first vehicle logo carrier and the second vehicle logo carrier, respectively, and the axes of rotation are both parallel to the longitudinal direction. That is, the vertical height changes generated by the first vehicle logo carrier and the second vehicle logo carrier when they move along the guide track are matched by the swing of the intermediate transmission member 204 relative to the output end of the linear drive mechanism.

[0069] Furthermore, the linear drive mechanism may specifically include a motor 201, a screw rod 202 and a slider 203. The motor 201 is mounted on the base shell 1, and the screw rod 202 is the output shaft of the motor 201. The motor 201 may specifically be a brushless motor 201 or a stepper motor 201. The slider 203 is threadedly connected to the screw rod 202 (the threaded transmission has a self-locking characteristic, which can keep the corresponding vehicle logo carrier stably located in the display track section 7), and at least one end of the slider 203 in the longitudinal direction is provided with a transmission shaft 205 rotatably connected to the transmission input end. Specifically, a transmission shaft 205 extending longitudinally outward may be provided on each of the two end faces in the longitudinal direction of the slider 203, and the two transmission shafts 205 are respectively rotatably connected to the transmission input end of the intermediate transmission member 204.

[0070] Further, see Figure 4 The intermediate transmission member 204 can be specifically a transmission plate 2041, which can be rectangular in shape. The transmission plate 2041 is provided with at least one downwardly extending transmission input arm 2042, which is configured to be rotatably connected to the output end of the linear drive mechanism (the number of transmission input arms 2042 can be two, arranged on either side of the transmission plate 2041 in the longitudinal direction and located in the middle region in the transverse direction. The lower ends of the two transmission input arms 2042 can be provided with shaft holes, thereby achieving rotational connection with the transmission shaft 205). At least one transmission output arm 2043 extending laterally outward is respectively provided at both ends of the transmission plate 2041, and the transmission output arms 2043 at both ends are respectively configured to be rotatably connected to the first vehicle logo carrier and the second vehicle logo carrier (the number of transmission output arms 2043 can be specifically four, which are respectively arranged at the four end points of the rectangular transmission plate 2041, and extend laterally at the corresponding end points in a direction away from the transmission plate 2041. The protruding end of the transmission output arm 2043 can also be provided with a rotating shaft for connecting to the corresponding vehicle logo carrier. The rotating shaft here can be set to be detachably connected to the transmission output arm 2043 for easy assembly).

[0071] See Figure 5In this embodiment, the first vehicle logo carrier and the second vehicle logo carrier are both vehicle logo carrier platforms 3. The vehicle logo carrier platform 3 is provided with at least one downwardly extending sliding extension arm 301, and the sliding extension arm 301 has at least one sliding end 3012 and a driving end 3011. The sliding end 3012 is configured to be slidably connected to the track guide part 4, and the driving end 3011 is configured to be rotationally connected to the transmission output end. The sliding end 3012 is vertically lower than the driving end 3011, and the driving end 3011 is arranged between the sliding end 3012 and the vehicle logo carrier platform 3, so that the height space required for the swing of the intermediate transmission plate 2041 can utilize the height difference between the sliding end 3012 and the vehicle logo carrier platform 3, that is, make full use of this part of the height space, so that the space required for the vehicle logo switching device as a whole in the height direction can be further compressed.

[0072] Specifically, each vehicle logo supporting platform 3 may have two sliding extension arms 301, disposed at either end of the vehicle logo supporting platform 3 in the longitudinal direction, corresponding to the first track plate 401 and the second track plate 402, respectively. Each sliding extension arm 301 may have two sliding ends 3012, disposed at either end of the sliding extension arm 301 in the transverse direction. The sliding ends 3012 may be pulleys configured to extend into and slidably connect to corresponding track grooves (the pulleys may include a connecting shaft connected to the sliding extension arm 301 and a bearing mounted on the connecting shaft, the outer ring of the bearing slidably connected to the corresponding track groove). Each sliding extension arm 301 may have one driving end 3011, located between the two sliding ends 3012. The driving end 3011 may be a rotating shaft hole provided in the sliding extension arm 301, configured to be rotatably connected to the rotating shaft on the transmission output arm 2043.

[0073] With the development of new energy vehicles, the demand for integrated and miniaturized internal components is increasing. In particular, space in the trunk of new energy vehicles, where the logo is located, is extremely limited. Furthermore, due to the unique front layout of new energy vehicles, the vertical space is relatively small, placing a high demand on the vertical height of the logo switching device. This embodiment, by combining the design of the logo switching motion trajectory with a specific structural design, effectively reduces the vertical height of the logo switching device, thereby meeting the demand for component miniaturization. Furthermore, the logo switching device typically displays two logos, one standard and one premium, special logo. Because the logo switching device of this embodiment switches between two logos via a horizontal reciprocating motion, compared to existing lifting and lowering switching methods, the switching path is shorter and simpler, significantly increasing the switching speed. Furthermore, if the premium, special logo on display is touched or damaged (which can be detected by the provision of a pressure sensor or other sensing structure), the device can automatically and quickly switch to the standard logo, effectively protecting the premium, special logo.

[0074] Example 2

[0075] This embodiment provides a control method based on the above embodiment 1, as follows:

[0076] like Figure 8 As shown, the present invention provides a vehicle logo switching device, including an MCU module and a current acquisition module, a motor transmission mechanism (i.e., the aforementioned drive unit), a sensor module, and a power supply module electrically connected to the MCU module.

[0077] The MCU module integrates a state detection unit, a drive unit and a current detection unit, and is used to obtain a target sensor signal, trigger a target control instruction according to the target sensor signal, drive the motor transmission mechanism to operate the main vehicle logo and the auxiliary vehicle logo switching working mode, and at the same time, respectively perform state detection and current detection and correction on the real-time state and real-time current during the vehicle logo switching process; wherein, the microcontroller internally integrates state detection, H-bridge drive, and current detection functions, completes state detection of the pressure sensor, recovery switch, and position switch, and realizes H-bridge drive and motor current detection; the current detection unit is used to detect the current size of the motor. When the detected current value exceeds a certain limit, the motor is stopped, thereby protecting the circuit.

[0078] The current acquisition module is connected to the current detection unit and is used to collect the real-time current signal generated during the vehicle logo switching process and feed it back to the MCU module;

[0079] The motor transmission mechanism is configured as an actuator for switching between the main and auxiliary vehicle logos via the motor drive module, and is used to execute the switching action between the main and auxiliary vehicle logos according to the target control instruction and feedback the switching status to the MCU module; wherein the motor transmission mechanism controls the conduction direction and conduction rate of the H-bridge, thereby realizing forward or reverse operation of the motor and controlling the motor operation rate;

[0080] The sensor modules are respectively arranged on the main vehicle logo and the auxiliary vehicle logo (can be respectively arranged on the first vehicle logo carrier, the second vehicle logo carrier or the vehicle logos corresponding to the two vehicle logo carriers), and are used to obtain sensor signals in real time and transmit them to the MCU module; it can be a pressure sensor / touch sensor integrated into the main vehicle logo LOGO. When a hand touch signal is detected on the main vehicle logo LOGO, the drive motor is activated and switched to the spare or auxiliary vehicle logo LOGO.

[0081] The power supply module is connected to the current detection unit through one path with the drive module and the current acquisition module, and is directly connected to the MCU module through the other path, and is used to convert the input vehicle body power supply voltage into a digital power supply voltage and supply power to each module; wherein, the status detection is a sensor signal or switch command that meets the vehicle logo switching trigger condition.

[0082] The vehicle logo switching device provided in this embodiment integrates status detection, drive and current detection functions through the MCU module, simplifies the circuit and improves the reliability of the device; the current is monitored in real time through the current acquisition module to ensure the safety of the motor; the sensor module ensures that the vehicle logo is accurately changed; the status detection unit responds to the trigger condition in time to prevent misoperation; the power supply module provides stable voltage to ensure the normal operation of the device and optimize the use of electricity; quickly responds to sensor signals to achieve accurate switching between the main and auxiliary vehicle logos, and monitors the current in real time, which helps to detect and handle abnormal situations in time and ensure continuous operation of the device. The flat design saves space and facilitates the integration of the control device into the limited space of the vehicle. Sensors and status detection are used to avoid damage caused by malicious destruction or misoperation.

[0083] Specifically, the motor drive module includes a motor and an H-bridge consisting of a first MOS transistor Q1, a second MOS transistor Q2, a third MOS transistor Q3, and a fourth MOS transistor Q4, which provides forward or reverse operation, speed control, and energy support for the motor. One end of the motor is connected to the collectors of the first MOS transistor Q1 and the fourth MOS transistor Q4, and the other end of the motor is connected to the collectors of the second MOS transistor Q2 and the third MOS transistor Q3. Different operating states of the motor are achieved by controlling the conduction and cutoff of the four MOS transistors. The H-bridge can also be composed of four switching elements, such as transistors, MOSFETs, etc. The motor is connected to the output end of the H-bridge, that is, connected between two diagonal switching elements. Different operating states of the motor are achieved by controlling the conduction and cutoff of the four switching elements. Taking a DC motor as an example, when Q1 and Q4 are turned on and Q2 and Q3 are turned off, the current flows from the positive pole of the power supply through Q1, the motor, and Q4 back to the negative pole of the power supply, and the motor rotates forward; when Q2 and Q3 are turned on and Q1 and Q4 are turned off, the current flows from the positive pole of the power supply through Q2, the motor, and Q3 back to the negative pole of the power supply, and the motor reverses. This can realize the forward and reverse rotation and speed adjustment of the motor to meet the needs of different working conditions. Switching elements such as MOSFET or triodes have the characteristics of low conduction voltage drop and high switching frequency, which improves the driving efficiency of the motor. The H-bridge circuit has a simple structure, stable operation, and reduced failure rate. Compared with other complex motor drive solutions, the H-bridge circuit has a low cost and is convenient for large-scale application.

[0084] Specifically, the power supply module includes a vehicle body power supply, an anti-reverse filtering module and a power management module. The output end of the vehicle body power supply is connected to the input end of the anti-reverse filtering module. One output end of the anti-reverse filtering module and the input end of the power management module are connected to the MCU module. Another output end of the anti-reverse filtering module is connected to the input end of the driving module. The output end of the driving module is connected to the input end of the current acquisition module. The output end of the current acquisition module is grounded and is used to output the original power from the vehicle body power supply, output the pre-processed power after the anti-reverse, filtering and overvoltage protection processing of the anti-reverse filtering module, and convert the input pre-processed power voltage into the target digital power supply voltage through the power supply module, and distribute the target digital power supply voltage to the next-level H-bridge and MCU module for power supply. The vehicle body power supply is not limited to 12V or 24V / 48V devices. The anti-reverse filter module provides power reverse protection, filtering protection, and overvoltage protection, while the output voltage supplies power to the next-level H-bridge and MCU. The input vehicle body power voltage is converted into a digital power voltage to power the MCU and other low-voltage modules. The power management module is not limited to a DCDC converter or LDO regulator, nor is it limited to being integrated inside or outside the MCU. The anti-reverse filter module effectively prevents power reverse connection to avoid equipment damage, while providing filtering and overvoltage protection functions. The power management module converts the vehicle body power supply into a stable digital power supply voltage to ensure reliable power supply to all parts of the device. The power management module includes any one of the following. The pre-processed power is distributed to the H-bridge and MCU modules on demand, optimizing power usage, improving energy efficiency, reducing the risk of failure due to power problems, and enhancing the overall safety of the device. It can adapt to the power characteristics of different vehicle models and ensure the compatibility and reliability of the device on various vehicles.

[0085] Specifically, the vehicle logo switching device provided in this embodiment further includes a position switch and a recovery switch;

[0086] The position switch sets the preset extreme position of the main and auxiliary vehicle logos for the corresponding travel respectively, and is used to detect whether the corresponding vehicle logo has reached the target switching position. When the main / auxiliary vehicle logo reaches the preset extreme position, the position switch is triggered and the motor stops running. The preset extreme position is the end position that can be reached under the switching travel;

[0087] The recovery switch is integrated into the vehicle cab. When the recovery switch is turned on and the position switch is detected to be triggered at the same time, the main vehicle logo returns to the starting position;

[0088] In order to achieve fast switching and reduce the time and steps required for switching, the main vehicle logo and the auxiliary vehicle logo are linked to each other so that the switching stroke has the vehicle logo switching state of AB stroke node linkage and BC stroke node linkage. In the first state, the target control instruction is received to drive the main vehicle logo from the starting B stroke node to the C stroke node to recover the main vehicle logo, and the auxiliary vehicle logo is driven from the A stroke node to the B stroke node to display the auxiliary vehicle logo; in the second state, the recovery instruction is received to drive the main vehicle logo from the C stroke node to the B stroke node to display the main vehicle logo, and the auxiliary vehicle logo is driven from the B stroke node to the A stroke node to recover the auxiliary vehicle logo, and the A stroke node is the auxiliary vehicle logo in the non-switching mode. The starting position of the logo and the logo recovery zone are hidden; the B trip node is the starting position of the main logo in non-switching mode and the target position of the secondary logo in switching mode, and is located in the center display area of ​​the vehicle, that is, the logo is exposed; the C trip node is the target position when the main logo is recovered in switching mode, and is hidden in the logo recovery zone. The linkage setting ensures the synchronization of the main and secondary logos during the switching process, avoids potential problems or errors caused by asynchrony, and achieves fast switching response efficiency when the logo is touched by external force, realizing efficient and stable logo switching function, which not only improves switching efficiency and system stability, but also optimizes user experience, making the logo switching process smoother and more natural. Figure 9 As shown, the above settings also ensure that the car logo can accurately reach the target position during the switching process, thereby improving the accuracy and reliability of the switching; the main and auxiliary car logos are linked to each other to achieve synchronous switching and recovery, thereby ensuring the integrity and continuity of the display; the recovery switch in the cab makes operation more convenient and reduces the complexity of operation; when the car logo reaches the preset position, it automatically stops to prevent overshoot or damage and improve the safety of the device; it can adapt to different display needs and can achieve rapid switching and recovery of the car logo through simple instructions.

[0089] To achieve rapid switching, the principle of this embodiment is as follows: in switching mode, when the pressure sensor / touch sensor is triggered by external pressure or a change in the touch state of the vehicle logo surface, a sensor signal is obtained and fed back to the MCU module. The MCU module then issues a target control command to drive the motor transmission mechanism, retrieving the main vehicle logo from the vehicle's central display area and simultaneously displaying the secondary vehicle logo in the vehicle's central display area, achieving rapid switching between the main and secondary vehicle logos. In implementation, one approach uses a capacitive touch sensor: when a conductor such as a human finger approaches or touches the vehicle logo surface, it changes the electric field distribution between the electrodes within the sensor, causing a change in capacitance. If a significant change in capacitance is detected and exceeds a set threshold, it can be determined to be a touch operation, thereby triggering a vehicle logo switching command. Another approach uses a resistive pressure sensor: using a Wheatstone bridge circuit structure, when external pressure acts on the sensor's elastic diaphragm, the resistance of the strain gauge resistor changes, causing the Wheatstone bridge to become unbalanced, and the output voltage signal changes accordingly. By measuring the change in the output voltage signal, when the change reaches a set standard, it is determined that pressure has been detected, thereby confirming external pressure and triggering the corresponding command. One method uses pressure-sensitive touch technology: combining a pressure sensor with a touch sensor. When a user touches the car logo, the touch action is first detected by a capacitive sensor, and then the pressure sensor detects the strength of the touch. If the strength reaches a preset threshold, the car logo switching instruction will be triggered. This technology can provide more accurate operation feedback, avoid false triggering, and achieve rapid switching within 0.5s.

[0090] In this embodiment, determining whether the pressure sensor / touch sensor is triggered due to external pressure or a change in the touch state of the vehicle logo surface is a process that comprehensively considers many factors, which are specifically described as follows: Setting threshold judgment: setting appropriate thresholds for the pressure sensor and touch sensor respectively. For the pressure sensor, when the detected pressure value exceeds the set pressure threshold, it is determined that effective external pressure has been received; for the touch sensor, when the detected signal strength, touch area and other parameters exceed the set touch threshold, it is determined that a touch operation has occurred. These thresholds are usually debugged and determined according to the actual application environment and needs. For example, when pressure is applied by an artificial external force, a suitable touch signal strength threshold is determined. Only when the touch signal strength is higher than the threshold will it be considered a valid touch operation, and then the command of opening the door will be executed, while non-artificial external forces such as branches and stones will be considered invalid touch operations.

[0091] Time characteristic judgment: The judgment is made based on the time characteristics of the signal. For example, a short, instantaneous pressure change or touch signal may be an interference signal and will not be responded to; however, a pressure or touch signal that lasts for a certain period of time is considered a valid operation instruction. The judgment of the signal's time characteristics can be achieved by setting a time window or using a filtering algorithm. For example, while driving, if the surface of the car logo is only touched briefly, the device may ignore this signal; but if the touch time exceeds a certain duration, such as more than 0.5 seconds, the device will determine it as a valid car logo switching instruction.

[0092] Signal change rate judgment: Calculate the change rate of the pressure or touch signal to determine whether it is a real operation. If the signal change rate is within a certain range and conforms to the logic of normal operation, it is considered to be a valid instruction; if the signal change rate is abnormal, it may be interference or misoperation. For example, when a finger quickly passes over the surface of the car logo, the change rate of the touch signal will be large. In this case, the car logo switching instruction may not be triggered. Only when the finger stably touches the car logo, the signal change rate is small and stable, and it will be regarded as a valid switching operation. The above method can improve the reliability and accuracy of the device by reasonably setting the threshold, analyzing the signal characteristics, and combining the vehicle status and environmental factors for judgment, providing users with a more convenient and safer use experience.

[0093] In the detection mode, the real-time status of the vehicle logo switching process is detected. When the pressure sensor / touch sensor is triggered by external pressure or the touch state change of the vehicle logo surface, the touch shutdown command corresponding to the current pressure sensor / touch sensor is identified to effectively prevent false triggering; the real-time current in the vehicle logo switching process is detected to determine whether the real-time current value has abnormal fluctuations during operation to ensure the safety of the motor operation and identify abnormalities when the current fluctuates to prevent foreign objects such as stones from getting stuck in the motor; in the abnormal mode, the fault handling mechanism is triggered according to the identified fault signal. When a false touch signal or the pressure signal of the external force does not reach the preset intensity threshold to form a false touch signal, the corresponding pressure sensor / touch sensor is diagnosed and calibrated through the MCU module; when a stall state other than a false touch signal is identified, a stop command is issued to the motor and corresponding protection operations are executed. After the stall fault is eliminated, a reset operation is performed to restore the normal working state, and software and hardware self-checks are automatically performed to optimize the running state. For example, if a motor malfunctions, such as overheating, abnormal speed, or inability to start, the MCU module will attempt to perform protective actions on the motor based on pre-set algorithms and logic, such as reducing power output, adjusting operating parameters, or attempting to restart the motor. If these measures fail to resolve the problem, the device will record detailed fault information and display a corresponding fault prompt to the driver through the vehicle's instrument panel or central control screen. It may also restrict further switching of the vehicle logo to prevent the fault from escalating. If a sensor malfunctions, such as a touch sensor continuously falsely reporting touch signals or a pressure sensor failing to accurately detect pressure changes, the MCU module will diagnose and calibrate the sensor, attempting to compensate for sensor errors using software algorithms or switching to a backup sensor. If a switching anomaly is caused by external interference, such as severe vibration or electromagnetic interference during vehicle operation, which affects the normal switching of the vehicle logo, the device will temporarily suspend the switching operation and wait for the interference source to disappear. At the same time, the MCU module will check and correct its own program execution status and clear erroneous data or status caused by the interference. Once the interference disappears and the device returns to normal, the logo switching operation will continue. If the interference lasts too long or the interference intensity is too strong, the device will send a warning message to the driver to inform him that there is an abnormality in the current logo switching.

[0094] Based on the same inventive concept, this embodiment also provides a vehicle, including the vehicle logo switching device as described in the above embodiment.

[0095] Based on the same inventive concept, see Figure 10 As shown, this embodiment also provides a control method for the vehicle logo switching device described in the above embodiment, including:

[0096] Power on and read the calibration data in the current running state. The calibration data includes the starting position, target position and key parameters of the vehicle logo during the switching process.

[0097] The main and secondary vehicle logos are reset to zero to ensure that they are at the calibrated starting positions before the switching action. For example, the starting position of the main vehicle logo is the B travel node, that is, located at the center of the vehicle center display area, and the starting position of the secondary coordinate is the A travel node, that is, the leftmost travel position. When switching, the main vehicle logo is moved from the B travel node to the C travel node, that is, the rightmost travel position, and the secondary vehicle logo is linked to move from the A travel node, that is, the leftmost travel position, to the B travel node to reach the display area. By returning the main and secondary vehicle logos to zero, the system ensures that each switching is performed under the same initial conditions, thereby improving the accuracy of the switching;

[0098] Receive target control instructions and determine whether to trigger the pressure sensor / touch sensor;

[0099] When the pressure sensor / touch sensor is triggered by external pressure or by a change in the touch state of the vehicle logo surface, the pressure sensor / touch sensor is triggered, and the touch-to-shutdown command corresponding to the current pressure sensor / touch sensor is valid; the touch-to-shutdown command here refers to an internal instruction or signal triggered by external input such as pressure or touch, which is used to control the vehicle logo switching operation.

[0100] When the current shutdown command is valid, the main logo shutdown command is executed, the motor drives the main logo to perform the switching operation, the travel information of the main logo from the starting position to the target position is recorded and the real-time current data is read;

[0101] Determine whether the current switching stroke exceeds the preset extreme stroke to prevent over-travel operation and ensure that the vehicle logo has been completely switched to the target position; only when the vehicle logo runs to a position exceeding the extreme stroke can it be ensured that the vehicle logo has been completely switched to the target state. If the current running stroke is less than or equal to the extreme stroke, the vehicle logo may not be completely switched, affecting the use effect and safety.

[0102] When the current switching stroke exceeds the preset extreme stroke, the logo switch in the cab successfully completes the switching operation between the main logo and the auxiliary logo, clears the touch-off command corresponding to the pressure sensor / touch sensor, stops the motor and puts it into standby mode. The above control method automatically reads the calibration data and judges the trigger conditions, realizes the intelligent control of the logo switching, ensures that the logo is in the starting position before switching, improves the accuracy of switching, records the stroke information and real-time current data, facilitates the monitoring of the logo switching process, prevents over-travel operation, ensures that the logo is completely switched to the target state, avoids damage, clears the touch-off command and puts the motor into standby mode, and improves the stability and reliability of the device. Among them, the current switching stroke refers to the route corresponding to the main vehicle logo from the B stroke node to the C stroke node and the auxiliary vehicle logo from the A stroke node to the B stroke node. The preset extreme stroke refers to the extreme position or maximum stroke range that the vehicle logo can reach during the switching process. By comparing the current running stroke with the extreme stroke, it is possible to accurately determine whether the vehicle logo has reached the target position. If the current running stroke is less than the extreme stroke, the device may mistakenly judge that the vehicle logo has been switched, thereby stopping the operation of the drive module, resulting in incomplete switching of the vehicle logo.

[0103] It can be understood that the control process described above reads the calibration data under the current operating state upon power-up and resets the main and auxiliary logos to zero, ensuring that the logos are in the predetermined starting position before each switch, thereby improving the accuracy and consistency of logo switching. The system can automatically receive target control instructions and intelligently execute logo switching operations based on the triggering of pressure sensors or touch sensors. This automated control reduces human intervention and improves the intelligence level of the system. During the switching process, the system records the main logo's travel information and real-time current data. This helps monitor the logo switching process, ensures smooth switching, and performs fault diagnosis when necessary. By determining whether the current switching travel exceeds the preset extreme travel, the system can ensure that the logo has been fully switched to the target position, preventing damage to the logo or incomplete switching due to overtravel operation. Clearing the shutdown command and placing the motor into standby mode helps protect the system from unnecessary energy consumption and wear, while also improving system stability and reliability.

[0104] Furthermore, the determining whether to trigger the pressure sensor / touch sensor includes:

[0105] If the pressure sensor / touch sensor is triggered, the shutdown command of the pressure sensor / touch sensor is valid, and the main logo shutdown command is executed through the logo switch in the cab, and the motor drives the main and auxiliary logos to switch, and records the travel information of the main and auxiliary logos from the starting position to the target position and reads the real-time current data;

[0106] If the pressure sensor / touch sensor is not triggered, it is further determined whether the received main logo off command is a command issued by the logo switch in the cab to prevent false triggering;

[0107] If the command comes from the in-cab logo switch, the motor will also be run to switch the primary and secondary logos. If the command comes from a different in-cab logo switch, the system will again check whether the pressure sensor touch-off command is valid. If it is, the motor will be run to switch the primary and secondary logos. If it is not, the system will return to the upper level and continue to wait for the target control command and repeat the subsequent judgment logic. This effectively distinguishes between the triggering of the pressure sensor / touch sensor and the command of the in-cab logo switch, avoiding misoperation and ensuring that only valid commands will execute the logo switch. This enhances the stability of the device. By recording travel information and real-time current data, the logo switching process can be accurately monitored, enabling appropriate judgments and processing based on different situations, thereby improving the device's intelligence level. The command issued by the in-cab logo switch here refers to the logo switching command actively triggered in the cab by the driver or vehicle control system. This command is issued via a physical switch, touch screen interface, or other electronic control method. By effectively distinguishing between the triggering of the pressure sensor / touch sensor and the command of the logo switch in the cab, misoperation is avoided, ensuring that only valid instructions will execute the logo switching, thereby enhancing the stability and reliability of the device; it can make corresponding judgments and processing according to different situations, such as the triggering of the pressure sensor / touch sensor or the command of the logo switch in the cab, thereby improving the intelligence level of the device; by recording travel information and real-time current data, it can achieve accurate monitoring of the logo switching process, which helps to timely discover and solve potential problems and ensure the smooth progress of the logo switching; it can further determine whether the received main logo shutdown command is a command issued by the logo switch in the cab, so as to prevent false triggering and improve the fault tolerance of the device.

[0108] Furthermore, the determining whether the current switching stroke exceeds the preset extreme stroke includes:

[0109] When the current switching stroke does not exceed the preset extreme stroke distance, the real-time current value obtained during the switching logo stroke is compared with the preset stall current value to determine whether the motor is in a stalled state;

[0110] If the current real-time current value is greater than the preset stall current value, the motor is in stall state and the fault diagnosis process is started;

[0111] Further confirm whether the current stall state is a fault. If it is confirmed that the current stall state is a fault, the motor stops and reports the relevant fault information to the ECU (Electronic Control Unit), which is the electronic control unit. Then, the pressure sensor triggers the shutdown command and enters the standby state.

[0112] If it is confirmed that there is no fault or the current is less than the preset stall current value, it will return to the upper level to continue waiting for receiving the target control instruction and repeat the subsequent judgment logic;

[0113] Among them, faults confirmed as stalled rotor include stalls caused by overvoltage, undervoltage, overcurrent, abnormal temperature, foreign objects in the switching stroke, and internal faults. The above judgment process monitors the motor status in real time, promptly detects potential problems such as stalls, and prevents more serious faults from occurring. Once a fault is confirmed, the machine is immediately shut down and reported to the ECU to avoid equipment damage or safety accidents. Accurately determine the cause of the fault, reduce misjudgments and unnecessary shutdowns, and improve the reliability of the device. It is convenient for maintenance personnel to quickly locate and solve problems, reducing maintenance costs.
